He was originally going to re-purpose one of his son’s RC cars, but didn’t want to risk breaking it. Instead, he designed a triangular 3-D printed chassis to hold a motor and some cogs to fit both the motor shaft and some re-used Meccano wheels. [Trandi]’s design employs an MPU 6050 6-DOF IMU for the balancing act and is built on an Arduino Nano clone.

[Trandi] is controlling the motor with an L293D, which has built-in flyback diodes to minimize spikes. He found that the Nano clone was not powerful enough to handle everything, so he added an L7805CV voltage regulator. After the break, watch [Trandi]’s cute bot tool around on various types of terrain, with and without a payload.

Cool project. I have a few L293Ds laying around…easy to use H drivers, but monitor your current limits (fried one already). I haven’t played with the MPU6050 yet but it looks pretty simple (and cheap!) I think I’ll order one as a late Xmas gift to myself. :)

Thanks Trandi – it sparked a few ideas. I love the clever design, especially the use of the small asprin/Rx/film/whatever container for the housing.

I want to make balancing robot with ır sonsor so;can you help me?
and ı took project about balancing robot and I must deliver for one month
I want your code and all document at your balancing robot.
Thank you in advance
